Title: Method and apparatus for controlling emitting power of semiconductor laser
Inventor: OGASAWARA KAN
IPC: H01S5/042
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to control the emitting power of a semiconductor laser at a low cost in a short time with high precision, and to automatize the adjustment as well. SOLUTION: In a trimmer 1, a standard laser power reference value is set and stored. Since the quantity of light emitted by a laser is in a large condition than a target power before trimming control, the trimmer 1 judges that it is larger than a target emitting power, and trims a trimmable resistor 2. Then the resistance value of the trimmable resistor increases, so that voltage value of the output Vm of a monitor amplifier increases also in proportion. And a laser driving circuit 54 decreases a current to be supplied to a laser, and the emitting power of the laser becomes lower than the time before the control, and approaches the target value.  Accordingly, trimming is continued until the emitting power or the semiconductor laser reaches the target value, APC- controlling the emitting power of the laser successively which changes successively by trimming operation, and detecting the front beam of the laser with a power meter.
